How to use

Select the connector tip that fits the device’s DC input port and attach it to the adapter cable. Set the output voltage to the value required by your device—verify the device’s rated input voltage before connecting. Plug the adapter into a mains outlet and connect the tip to the device; monitor the device briefly after first connection to confirm proper operation. When switching between devices, disconnect from mains, change the tip and voltage setting, then reconnect.

Usage recommendations

Always confirm the device’s required voltage and polarity before use. Avoid operating the adapter continuously at maximum power for prolonged periods without adequate ventilation. Use only the supplied interchangeable tips or compatible replacements, and disconnect the adapter from mains during tip changes.
